Eh... she's okay. Not exactly my favorite... but I see your point, she does look a tad creepy She kinda looks like an old lady wearing one of those big flower hats lol.
Well, I'd say the creepiness definitely comes from her make-up. But hey, what tamagotchi doesn't look creepy with make-up on? If you use the mirror and make-up in the V4.5 or V6 (maybe other versions too, but I wouldn't know), you get instant nightmare fuel.
She reminds me of the old ladies that are very prudish and wear strong floral prefume while shielding their delicate skin from the harmful UV's with their big hats. That's what I think.
